Abstract: Filler bodies for the biological purification of, for example, waste water are fitted together from individual filler-body blocks. In this case, these have to be releaseably connected to one another. In known filler bodies, adapters are used for this purpose which obstruct the ability of the waste water to flow through or around the filler body. As a result, the cleaning capacity is also reduced.      The filler body according to the invention has at least one tube of one or each filler-body block (21, 22, 23, 36, 40, 45) as a tube (31, 37, 38, 39, 56) which extends over a plurality of filler-body blocks (21, 22, 23, 36, 40, 45). As a result, the individual filler-body blocks (21, 22, 23, 36, 40, 45) are connected to one another in a positive-locking manner without the ability to flow through or around the filler body being obstructed.      The filler body according to the invention is particularly suitable as a substrate for a so-called biological lawn for the biological purification of waste water or gases.

Abstract: A conjugate of a carrier polymer and aziridine ring containing mitomycin (MMC) drug molecules is prepared by coupling the MMC molecules via their aziridine imino groups to spacer groups that terminate in protected amino groups, deprotecting said amino groups, recovering and purifying the spacer-MMC derivatives, and then coupling these derivatives via said deprotected terminal amino groups to the carrier polymer.  Alternatively, the MMC may first be treated with an activating agent, e.g. carbodiimidazole, to form on activated MMC derivative which is then coupled directly to spacer groups linked to the carrier polymer.

Title: Arbitrary-geometry laser surface scanner
Inventor: MCCALLUM BRUCE CLINTON
IPC: G01B11/00
Filed: 1995-09-28
Granted: 2002-11-12
Abstract: An optical non-contact surface scanning method and system is described. The three-dimensional coordinates of an illuminated profile or spot on the object are recorded and the surface is reconstructed using spatial location and orientation information derived from a spatial location system associated with the object, illumination means, and image recording means. The illumination and imaging means may be hand-held in a combined unit or in separate units.  The scanning system allows complete free and arbitrary movement of the object and all components of the scanning during scanning this allowing scanning of substantially all of the surface which may be visible at various locations and orientations around the object. The optical non-contact scanning system may find particular application in medical imaging of the human body or parts thereof. It may further find application in industrial processes whereby the passage of arbitrarily shaped objects are monitored through a production line or similar situations.

Title: Restoration of concrete decks
Inventor: WHITMORE DAVID W
IPC: E01C7/14
Filed: 1997-06-13
Granted: 2005-01-18
Abstract: Restoration of a concrete roadway is effected by application onto the upper surface of the roadway of steel sheets which are used as an anode for electrolytic transfer of ions between the anode and the reinforcing bars of the concrete as cathode. The steel sheets are placed in effect directly on top of the concrete surface so as to communicate forces from the traffic to the concrete surface without the necessity for separate support of the sheets. An intervening layer may be formed of particulate material, a very thin felt or there may be no intervening layer. The sheets can be formed by two layers of steel with the upper layer embossed and the edges offset so as to define flanges allowing the sheets to be bolted together.
